Riverside Geyser

Description

Situated on the bank of the Firehole River, Riverside Geyser is one of the most picturesque geysers in the park. During its 20-minute eruptions, a 75 foot (23m) column of water arches gracefully over the river. Eruptions are about 5-1/2 to 6-1/2 hours apart. There is water runoff over the edge of Riverside's cone beginning 90-135 minutes before an eruption.
